Gently melt 3.5 ounces of sugar-free chocolate with 1 tablespoon of coconut oil until it's smooth and glossy. You can easily do this in a microwave-safe bowl, stirring every 30 seconds, or by setting a bowl over a pot of gently simmering water.
Pour half of the melted chocolate into your chosen silicone molds (heart shapes or small muffin cups work perfectly!). Swirl or use a small pastry brush to make sure the bottom and sides are fully coated. Pop the molds into the freezer for about 5-10 minutes to let the chocolate set firm.
While your chocolate shells are chilling, get ready to make the delicious filling. In a food processor, blend the 6 ounces of roasted pistachios, the remaining 4 tablespoons of coconut oil, 1 teaspoon of vanilla extract, and liquid stevia to your desired sweetness. Process until it forms a smooth, creamy butter. Once blended, gently fold in the 3.5 ounces of dried coconut flakes for that irresistible crunch.
Once your chocolate shells are firm, evenly spoon the pistachio crunch filling into each mold. Then, pour the remaining melted chocolate over the filling to create a smooth top layer. Place the molds back in the refrigerator or freezer until completely set, which usually takes about 1 hour. Once firm, simply pop them out and enjoy your delightful, homemade Dubai chocolate!
